He finds, its apparent Motion was not made in a Juft great 
Circle, but deviating conflderably from it $ and conceives, 
that every Comet falls to this deviation, when this apparent 
Motion grows flow, and the Star becomes Stationary (which, 
as he faith, it'doth in .refpe&of the Ecliptic k^^ not its own 
Or bite.) Here he obferves. That from Deae/nb. ,* ; to Decern. 
§0. Jdn.g. its courte was almoft in a great Circle : but, that 
then it began to defied from that Circle towards the North 5 
fothat afterwards, with a very notable and confpieuous 
Curvity, it dire&ed its courfe towards Trimam Arietis : Of 
which dcflt&ion, he ventures to affign the caufe from the 
Cometical Matter, the various pofition and di (lance of the 
Comet from the Earth and the Sun, the annual Motion of 
the Earth, and the imprefled Motion, and the inclination 
of the difcusof the Cometical Body. 
He is pretty pofitive, that without the annual Motion of 
the E*rth 9 no rational Account can be given of any Comet, 
but that all is involved with perplexities, and deform’d by 
absurdities* 
He inquires, fjnceall Comets have their peculiar Jngenite 
Motion, what kindeof Line it is* they defcribe by that 
Motion of their own ^ whether circular , or (freight, or 
curve, or partly (freight and partly curve .<? And if curve, 
whether regular or irregular? if regular, whether EHiptlck, 
or Parabolar, or Hyperbolical ? Heanfwers, That this Mo- 
tion is Conical s and judgeth, that by the Conick, path all 
the rh<£ntwiena o£ Comets can, without any inconveniency, 
be readily folved 5 even of that, which by Hiftory ) in fifty 
days, palled through more then the I* Signs of the ZoJidck: 
And of that, which in two days run through eight Signs : 
and of another, which in 48 days polled through all the 
Signs, contra fcriern . Which how it can be explicated upon 
the fuppofituin of the Earths (landing (fill, and upon ihe 
denying of the annual Motion thereof, he unda ftands not 
at all,
